Biography - Click Here

I received my PhD in Geography (GIS, remote sensing, and spatial analysis) in 2010, MS in Agronomy (soil chemistry) in 2002, and BS in Agronomy and Genetics in 1991.  Throughout that entire time period, the theme of environmental science has run through my academic work.  After receiving my BS, I served two years in the Peace Corp in Paraguay.

Research in The Iron Lab
We are finishing up the writing for submission of the work of Jackie Campbell and Lori Schneider on the removal of iron from transferrin. Additional work was carried out after they left, but these additional studies will make this a superb paper. Jackie has now passed her prelims in the Department of Microbiology and Immunology, Vanderbilt University School of Medicine, and is now a Ph.D. candidate. Congradulations to Jackie. Lori has successfully completed two semesters at Iowa State University School of Veterinary Medicine and is thinking about a career in research. This likley means a Ph.D. after her DVM should she decide to go this direction.

I had a good summer studying Advanced Bacterial Genetics at Cold Spring Harbor Laboratory. The course was intense but very good. Research in the lab is centering around the thermodynamics of the transfer of iron from various chelators to bacterial siderophores, and learning more about bioinformatics and molecular modeling. Plans are also being made to get back to isolating and characterizing bacterial iron reductases.

Biography - Click Here

Turner is  pursuing a doctorate at National Louis University while teaching education, science, and research classes at University of Dubuque and  National Louis University.

He led teams of teachers and students in research on local wetlands, fullerenes, liquid crystals, piezoelectrics, lighter-than-air solids, diamond thin-films, and more.  He has taught Materials Engineering and Design at the Cray Academy (Eau Clair, WI) and at the Center for Talent Development (Northwestern University). He initiated, led, and published two different integrated curriculums. He has years of experience teaching high school and middle school sciences, and holds certifications in high school and elementary teaching in addition to being a National Board Certified Teacher. 

He is a module developer, beta tester, book author, and workshop leader for Materials World Modules, at the Materials Science Institute, Northwestern University. He has authored articles, participated in nationwide validity studies, directed a Toyota Tapestry project, led workshops from Boston to San Francisco, and won Illinois “Those Who Excel” award for excellence in teaching three times.

He has been published in The Science Teacher, Journal of Chemical Education, Journal of Materials Education, and others.  He published, “Ready for the Next Generation Science Standards” at the Iowa Academy of Science (2014), and will present “Formative Evaluation of Preparedness to Teach Engineering Design and NGSS” at Evaluation 2014, the national conference for the American Evaluation Association.  He has researched, published, and taught Engineering Design for over a decade.

He believes that, as never before, our students, teachers, and leaders will need to bring all of their creativity and intelligence to bear on each problem they face. Therefore, integrity, collaboration, and innovation must mark our efforts in school and personal improvement. It is a moral imperative.
